To all whom it may concern:

Be it known that l, JOSEF MARIAN, a sub ject of the King of Hungary,residing at Fressburg, in the Empire of Austrialtilungary, haveinventedv certain new and useful improvements in Bottle-Closures, ofwhich the following is a specification.

'F he present invent-ion relates to a bottleclosure, more particularlyfor milk-bottles, and its object is to provide improved means foreffecting the closing of a bottle in such a manner that any unauthorizedinjury to the closure is immediately visible, the closure being,nevertheless, easy, simple, and cheap to produce. l

With the improved closure a bottle is used, pro-vided in the knownmanner with a groove inv its neck, said closure consisting of a capwhich covers the mouth of the bottle and consists of suitable softmaterial, such 'as parchment, paper or the like with a ring or sleeve ofthe same or similar material surrounding the depending wall o-f the cap,but not integral with the cap. For closing the bottle, the lower edgesof the cap and the' surrounding sleeves are pressed into the groove inthe bottle-neck and folded into a U-section in said groove.

'lhis bottle-closure is illustrated in the accompanying drawings, inwhich- Figure l is a sectional elevation representing the known form ofbottle, provided with a groove of rectangular cross-section in the neck.Figs. 2 to 4 are sections of the cap. Fig. 5 is a sectional elevationshowing a bottle with the cap loose thereon, and Fig. 6 is a similar1{iew showing the bottle with the cap fastened. y

The bottle (Fig l) has at its neck a a narrow, deep, groove b ofrectangular cross-section. This groove serves to take the side wall ofthe cap, which is folded thereinto with the sleeve.

'llhe cap is formed as a capsule of any suitable material, such aspaper, parchment and the like. Fig. 2 shows in cross-section a simplecap c, prior to the placing of the sleeve thereon.,

Fig. 3 shows a cap c1 with the reinforcing ring or sleeve d of metal,card-board, or other strong material placed thereon, the cap having 1nthis case a small flange e for supporting the reinforcing ring d, thelatter is cut from a thin-walled tube and slipped on tothe cap, thedimensions being so roportioned that the parts t snugly toget er.

flhe wallof the cap may itself be reinforced independently of the ringal which is placed thereon. V Fig. 4C shows a cap 02 the edge of whichis inwardly bent, the folded portion j forming the reinforcement, anarrangement which 1s, forV example, suitable 'in the case of caps ofvery thin material. ft is, however, -obvious that the nature of thereinforcement is not confined to any particular material. v lln order tofold the cap into the groove the former is placed on the bottle as shown1n Fig. 5 the sleeve d being placed on the cap before or after thelatter is placed in i position, whereupon the side wall and the sleeveare pressed into the groove b. To allow of doing this, said side walland sleeve must overlap .the groove to such an extent that there issufficient material to enable the edge to enter the groove and to befolded therein into U-shape, as indicated in Fig. 6, but after thefolding, no portion of the cap or sleeve remains pendent below thegroove, so that no loose edge is available by means of which the foldedmaterial can be drawn out of the groove. By the pressing and consequentformation of folds it is rendered impossible to remove the cap withoutdetection, since any tampering with the cap results in partialdestruction thereof, so that the attempt is immediately disclosed.

llt will therefore be seen that a simple, quickly and cheaply madeclosure is provided, which immediately shows evidence of unauthorizedtampering, and is fully adequate for the purpose for which it isdesigned.

'llhe sleeve d slipped over the cap gives the closure a strength whichcould only be obtained by using a cap of tough and stid material in theabsence of the sleeve. With suchmaterial the breaking of the closurewould of course be more or less difficult, whereas the sleeve ai can betorn at its upper edge and drawn out of the groove and thus releases thecap without violence and without risk of introducing broken pieces intothe bottle in the course of the opening process.

What ll claim as my invention and desire to secure by Letters Patentvofthe United States is 1 A bottle closure comprising a cap of exiblematerial adapted to be placed over a bottle neck provided with anannular groove,

and a sleeve of flexible materialsurrounding the side Wall of said cap,the said `sidel specification in ythe presence of two Wit- `wall of thecap and slleve being folded tonesses. gether so as to interloc and forma substan'- w tially-U-shaped inwardly projecting annular JOEF- MARIAN'5 bead snugly ttng in the annular groove of Witnesses:
